Testing and Debugging

Motivation: Ensuring the website functions correctly and is free of errors is essential. This section outlines the testing and debugging process for the Coming Soon website, focusing on codebase structure and procedures.

Testing:

• Unit Tests: These tests focus on individual components or functions of the codebase. Unit tests are crucial for verifying the correctness of each part independently.
  • Example: A unit test for a function that calculates the sum of two numbers would ensure that the function returns the correct result for various input combinations.
• Integration Tests: These tests verify the interaction and communication between different parts of the application.
  • Example: Testing the interaction between a user interface component and a backend API.
• End-to-End Tests: These tests simulate real-user scenarios and verify the functionality of the entire application from start to finish.
  • Example: A test that simulates a user signing up for an account, verifying that the sign-up process is successful and the account is created correctly.

Debugging:

• Logging: Implement comprehensive logging to track the execution flow and identify potential errors.
  • Example: Logging important events, function calls, and variable values can provide valuable insight into the cause of errors.
• Debugging Tools: Leverage debugging tools integrated into the development environment or browser to step through code execution, inspect variables, and identify issues.
  • Example: Using the browser’s developer console to set breakpoints and examine the code’s behavior at specific points.
• Error Handling: Implement robust error handling mechanisms to catch and gracefully handle potential exceptions.
  • Example: Displaying informative error messages to users and logging error details for future investigation.

Codebase Structure:

• Test Files: Tests are typically stored in separate files or directories within the project structure, organized by functionality or component.
• Testing Framework: The project utilizes a dedicated testing framework to streamline test execution and reporting. The framework provides methods for defining tests, asserting expected outcomes, and generating reports.
• Debugging Tools Integration: The development environment is configured with debugging tools that allow developers to step through code, examine variables, and identify issues.

Example:

// Example unit test:
          function add(a, b) {
            return a + b;
          }
          
          test('adds 1 + 2 to equal 3', () => {
            expect(add(1, 2)).toBe(3);
          });
          
          // Example debugging code with logging:
          function calculateDiscount(price) {
            console.log('Calculating discount for price:', price);
            if (price > 100) {
              return price * 0.1;
            } else {
              return price * 0.05;
            }
          }
